Effective dose (E), representing the risk of late radiation-induced effects, can be estimated by the use of conversion factors (CF), converting direct measurable quantities such as dose-area-product into E. Eight Belgian hospitals participated in the study with a total number of 318 procedures. E-values, calculated with PCXMC, were compared for the different hospitals for diagnostic and therape...

to be sure, that a program behaves correctly at runtime; the behavior of the program should be verified. where the program source code is available, it is possible to extract the operational logic (i.e., behavior) of the program. but in this paper, programs are considered as black boxes, so no information is available about the operational logic of programs. however, some efforts are spent to l...

Purpose To compare patient radiation doses in cone beam computed tomography (CBCT) of two mobile systems used for navigation-assisted mini-invasive orthopedic surgery: O-arm®O2 and Surgivisio®. Methods The study focused on imaging the spine. Thermoluminescent dosimeters were to measure organs effective (ED) during CBCT. An ionization-chamber a solid-state sensor incident air-kerma (Ki) at cente...

Introduction: Nowadays ionizing radiation has a considerable contribution in medical diagnostic and treatment. Using ionizing radiation is increasing rapidly, so biological effects of ionizing radiation should be considered more. X-rays in the range of diagnostic radiology have hazardous effects and risks that are defined as random effects. These effects obey the LNT hypothesis that occur at lo...

ôbjective: the current research tested the differences in reading attitude and reading comprehension in the dyslexic students between the control group and the experimental group following the barton intervention program. methods: dyslexia screening instrument and reading text were employed in order to identify dyslexic students. the population of the study included 138 dyslexic students studyi...
